[OpenID] An OpenID "mobile" Hint?

[David Recordon]

Agreed, in a perfect world you'd have lots of OPs with mobile  
experiences.  I guess part of what I'm thinking about is far less  
around the technology and more around a forcing function to make it  
very clear about which OPs support mobile and which don't.  In the end  
hopefully getting us to that perfect world.
